CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 232,149, datedSeptember 14, 1880. Application filed April 24, 1880. (No model.)

To all whom it may concern:

Be it known that I, EDGAR RoBINsoN, of Columbus, in the county ofFranklin and State of Ohio, have invented a new and valuable Improvementin Oar-Axle Boxes; and I do hereby declare that the following is afull,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a longitudinal vertical section of myimproved car-axle box. Fig. 2 is a transverse section of the same. Fig.3 is a top view of the same, with the equalizer in section; and Figs. 4and 5 are perspective views, respectively, of the lower and upperbearings.

This invention has relation to car-axle boxes; and it consists in theconstruction and novel arrangement of parts, as hereinafter shown anddescribed.

In the accompanying drawings, the letter A designates the case or bodyof thecar-axle box, the sides of which are connected by a transversebridge or bearing, B, having a spring connection or catch, a, whichengages a lug, I), on the upper surface of the cover O, which slidesinto the case from the outer or front end freely under the bearing B,its sides 0, which are preferably beveled, working in slide= grooves dinthe upper portions of the sides of the box.

The front of the cover G is made with side guides, D, and a slidegate,E, designed to be raised when it is desired to inspect the interior ofthe box. To this gate is secured an angular springcatch, c, whichengages with. the front end of the cover and holds the gate down. Theend of this spring passes through an openin g, f, in the gate, andserves as a handle whereby the catch can be released and the gateraised, when the spring, returning to its position, will hold the gateup by its engagement with the upper edge of the front of the cover.

In the lower portion of the box is the oilcavity F, having extendinginto it a spindle, g, on the end of a spring, g, or other form ofspring-bearing connected to the inner portion of the box, to receive theoil-roller k, which is arranged to slide on the spindle toward the frontof the box, to allow the splash-box G, which covers the oil-cavity underthe journal, and which has an opening, I, through which the roller worksagainst the journal H, to be readily removed when necessary.

From the lower part of the inner end of the box extends upward, underthe axle, a semicircular flange, m, raisingthe inner boundary of theoil-cavity to, or nearly to, the axle, and thereby increasing itscapacity, as well as preventing undue leakage at this end of the box,which is apt to occur when an open space is left under the axle in themargin of the box, as is commonly the case when the box is raised bodilyin releasing the brasses. Above this flange is the inner slide-plate, K,which closes the inner end of the box over the journal. Outside of thisplate, and through the inner ends of the side walls of the box, frompoints a little below the level of the top of the journal, are arrangedvertical transverse slots or bearings s, which receive a transversewedge, L, which extends across the axle, bearing on the same, so thatwhen it is desired to release the cover and brasses from the pressureabove it is only necessary to insert this wedge and strike its largerend a smart blow.

R indicates the upper or outer brass or bearing, which is next the coverof the box, lying underneath the same and upon the lower brass orjournal-bearing, T. These brasses are usually provided with verticalguides n, which keep them in position, the upper ends of these guidesbeing sufficiently below the bridgebearing B of the box to allow theMasses to be raised clear thereof and withdrawn when the sliding coverhas been removed. The up; per brass, R, is made with a downward flange,1', serving as an inner guard or abutment.

Having described this invention, what I .claim, and desire to secure byLetters Patent,

1. The combination, in a car-axle box, with the transverse bearing B andits catch a, of the sliding cover 0 and its catch-lug 1), substantiallyas specified.

2. The combination, with a car-axle box and its wedge-bearings s, of thetransverse liftingwedge L, adapted to bear on the axle, substantially asspecified.

3. In a car-axle box, the combination, with the side walls having slotsfor a wedge over the inner journal-aperture, the sliding top or cover C,and the oil-chamber F in the bottom part, of the semicircular oil-flangem, extending upward to the journal, serving to transfer the bearing fromthe upper to the under side of said journal when the brasses are to beremoved and to prevent the undue escape of oil, as shown and described.

4:. In a car-axle box, the removable splash box G under thejournal, andhaving an open ing, Z, in combination with the sliding oil-roller 7c andits spring-bearing, substantially as specified.

5. The combination, with the top of an axleboX and the sliding gate E,of the angular spring catch 0, extending by its free end through thegate and serving to hold the latter either down or in the raisedposition, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
